Abstract: In current paper we consider new polynomials, generated by orthogonal on uniform grid Chebyshev polynomials. Newly introduced polynomials are themselves orthogonal with respect to the Sobolev-type inner product. The explicit form of these polynomials, convenient to study their asymptotic properties, is obtained.

Keywords: orthogonal polynomials, Sobolev-type orthogonal polynomials, Chebyshev polynomials.
